Here's an insane story for your Monday: Over the weekend, a man was arrested at a Beyonce and Jay Z concert at the Rose Bowl in Pasadena, Calif., after he bit off a man's fingertip, the San Gabriel Valley Tribune reports.

Twenty-five-year-old Roberto Alcaraz-Garnica allegedly groped a twenty-something woman during the show on Saturday night (Aug. 2), and got into a physical fight with the woman's boyfriend after the man confronted him. It was during the altercation that Garnica bit the man, "causing serious injury to his finger," Pasadena Lieutenant John Luna told the Tribune, noting that the victim "lost the tip to one of his fingers."

Alcaraz-Garnica was arrested on suspicion of "sexual battery and mayhem," and is being held on $100,000 bail.

Police reportedly made 10 other arrests during the show, including eight for public drunkenness and two for ticket scalping, though Alcaraz-Garnica's clearly remains the most disturbing -- and quite frankly, gives a whole new meaning to the 'On the Run' tour.

Sadly, this new comes less than a week after a man was charged with raping a woman at a Keith Urban concert -- the same show where more than 20 people were hospitalized for alcohol-related issues.
